Single-Pedal Parking Control With Electronic Handbrake Coordination

The patent introduces a vehicle controller as an intermediary that coordinates between the accelerator pedal input and the motor controller. The vehicle controller processes the single-pedal input signals and generates appropriate deceleration control commands, acting as a mediator that enables effective deceleration control while maintaining single-pedal operation simplicity.

The patent replaces traditional mechanical brake pedal operation with an electronic control system. Instead of requiring mechanical brake pedal input, the system uses electronic signals from the accelerator pedal position sensor and motor controller to achieve deceleration, substituting mechanical braking with electronic motor control.

The patent implements dynamic control of motor torque to achieve deceleration. Instead of applying fixed brake force, the system dynamically adjusts motor torque based on vehicle speed, accelerator pedal position, and driving conditions, allowing for energy-efficient deceleration that recovers kinetic energy while maintaining effective speed reduction.

The patent changes the control parameter from binary brake on/off to continuous motor torque adjustment. By varying motor torque parameters based on accelerator pedal position and vehicle state, the system achieves smooth deceleration with optimized energy utilization, transitioning between different torque levels rather than applying fixed braking force.
